What the tools do with your data

Nothing you type into a calculator on this site is transmitted anywhere. Every tool is implemented in JavaScript that runs inside your browser: the frames, register values, and messages you paste are processed locally and are never uploaded to a server, logged, or stored. Closing the tab discards them.

Information collected automatically

Like most websites, this site's hosting provider records standard server request data — IP address, browser user agent, referring page, and the time of the request. This is used to keep the site running and to understand which pages are useful. It is not linked to any identity.
